• Compaq NT

• Digital Unix

• SNI Reliant Unix

• Sun Solaris

• SNI NT

• HP NT

• Digital NT

• IBM OS/400

• IBM NT

• Bull AIX

• NCR NT

• Sequent Dynix

• IBM S/390

• DG-UX

• DG NT

• NCR Unix

• ZDS

• Intergraph

• Hitachi

• AST

• Dell

• Fujitsu

• NEC NT

7.2. Reinitialize R/3

• Check authorizations for SAP using SU02.

• Delete SAP* user under Oracle:

  connect internal delete from sapr3.utab where tabname = 'USR02' and varkey = '000SAP*'; commit;

• Log in as SAP*, password 06071992. (The default password for DDIC is 19920706; the default password for SAPR3 is SAP)

• Use txn SU01 to recreate authorizations in SAP* user record:

  • SAP_ALL

  • SAP_NEW

  • S_USER_ALL

  • S_TSKH_ALL

7.3. Useful ABAPS

• RSREGEN

  This program regenerates all ABAP programs. It must be run as user SAP*.

• SAPMSOS0

  This program can be used to somewhat interactively execute programs at the operating system level. It appears to have been omitted in version 3 and above...

• RSQAPIDF

  Job Queue API

• RSBDCSUB

  BDC API

• RSCLRCMP

  This program compares tables between the client you are logged into, and another client you specify for client independent tables.

• RSCLIIND

  Compare client-dependent tables.

• RPUMKG00

  Regenerate features

  Transport of a "feature" (heaven only knows what a feature actually is) is indicated by transport of an object of type R3TR and PMKC.

  Activation ("regeneration") of features is not handled automatically at the time of transport; this is likely something that will be added to CTS functionality some day by SAP AG. Thus the need to run program RPUMKG00. The appropriate argument to pass in seems usually be to generate all features, with a Type of generation value of "2."

• RSCCPROT

  Client Copy Log Analysis

  See when/where client copies have taken place.

    form test.
    data:
      typ(1) type c,
      n type i.
    field-symbols: <f>.
    
       do.
         assign component sy-index of structure itab to <f>.
         if sy-subrc <> 0. exit. endif.
         write <f>.
       enddo.
    endform.

7.4. Payroll Programs

• RPCLST**

  Examine cluster **.

• Function Module Z_LGART_RPT.

  Pass in the payroll class and info on desired values

  Passes back a variety of tables representing breakdowns of spending for the

• ZHPYRPTS - Example template for Retro Net wagetype reporting

  Must have FORM Z800_ACCUMULATE_DATA, which collects data from internal table NETRT into whatever program structure is defined to accumulate data for later use in reporting. Called from INCLUDE ZHPYI012.

7.5. Schemas

A little "rule language" for representing pay calculation rules as used in programs RPCALC*. The US Payroll calculation program is RPCALCU0.

The U000 scheme is used to estimate payroll calculations; it is run repeatedly on a group of employees until no exceptions are found.

7.6. Payroll Run: RPCALC*0

One can characterize the calculations for scheme U000 as doing the following:

• Validate Basic information ( e.g. infotypes 0001 thru 0009)

• Read payroll account for the period last processed

• Read time data

• Build up individual and aggregate gross income

• Filter out deductions

• Deduct previously calculated amounts (what shall be "type P" records) so as to determine the "net" amount. They must be deducted "twice" rather than once...

• Determine the amount that must be turned into a "bank transfer."

Once the data is correct, use scheme U500 to create an FI export to be used to account for the payroll activity in the G/L.

There are three "input files" used to calculate payroll:

• Pnnnn ( nnnn is the infotype number)

  Personnel master record info

• PCL1 - Primary data - time events

  • B1 - Time events/pdC

  • G1 - Group incentive wages

  • L1 - Individual incentive wages

  • PC - Personal Calendar

  • TE - Travel expenses/payroll results

  • TS - Travel Expenses/master data

  • TX - Infotype texts

  • ZI - PDC interface for cost accounting/materials management

• PCL2 - Secondary data - derived from Pnnnn and PCL1 for previous months

  • B2 - Time accounting results

  • CD - Cluster Directory

  • PS - Generated schemas

  • PT - Texts for Generated schemas

  • RX - Payroll results - int'l

  • Rn - Payroll results - country specific

  • ZL - Personal work schedule

• PCL3

  • AP - Applicant actions

  • TY - Texts for applicant data infotypes

RPCALC*0 is used to turn these into a new PCL2 record containing current period payroll data; the Pnnnn data is archived for future reference...

While working, the following internal tables are used:

• IT - Input Table - containing wage types

• OT - Output Table - contains results of processing; gets fed back into IT after each processing step

• RT - Results Table for the accounted period

  After completion, this data is stored in cluster RX of PCL2.

• ORT - Old Results Table - the contents of RT in the previous period's run

7.7. Useful Function Modules

7.9. Finding User-Exits

Transaction SMOD can list R/3 user exits; use the second screen to specify a range, from 11111111 to zzzzzzzz.

Most user exits are function modules containing EXIT_.

7.10. Useful Tables
