Let first introduce the SAP Tables used for Production:

PLKO: Task list – header
PLPO: Task list – operation/activity
PLMZ: Allocation of bill of material items to operations
PLAS: Task list – selection of operations/activities
PLAB: Relationships
PLAF: Planned order
PLFH: Task list – production resources/tools
PLFL: Task list – sequences
PLFT: Process Instructions
PLFV: PI Characteristics/Sub-Operation Parameter Values
PLKV: View of planned order header data
PLKZ: Task list: main header
PLMK: Inspection plan characteristics
PLMW: MAPL-Dependent Charac. Specifications (Inspection Plan)
PLPH: CAPP: Sub-operations
PLPB: Long-term planning: Independent requirements versions
PLPW: Index of the production/delivery plant in the planned order
PLSR: Scheduling results
PLST: Status table for planned order processing
PLZU: Routing data for group

The next step is how to link between theses SAP main tables in SAP PP.

Main Keys fields for

The Main keys fields for are:

PLNTY Task List Type Number (for orders from AFKO, for notifications from QMIH)
PLNNR Group (for orders from AFKO, for notifications from QMIH)
PLNAL Group Counter (for orders from AFKO, for notifications from QMIH)

Link between PLKO and PLPO

This section will cover the relationship between PLPO and PLKO.
The link between PLKO : Routine Header and PLPO Routine Post is done in the table PLAS.

An example of SAP Select how to retrieve PLAS – Link between PLPO and PLKO

*----------------------------------------------------*
* READ PLAS
*----------------------------------------------------*
IF NOT lt_plko[] IS INITIAL.
SELECT * FROM plas INTO TABLE lt_plas
FOR ALL ENTRIES IN lt_plko

AND plnnr = lt_plko-plnnr
AND plnal = lt_plko-plnal
AND loekz NE 'X'.
DELETE ADJACENT DUPLICATES FROM lt_plas COMPARING ALL FIELDS.
ENDIF.

FOR ALL ENTRIES IN lt_plko

WHERE plnty = lt_plko-plnty

AND plnnr = lt_plko-plnnr

An example SAP Select to retrieve the PLPO with the PLAS-link to PLKO.

*----------------------------------------------------*
* READ PLPO
*----------------------------------------------------*
IF NOT lt_plas[] IS INITIAL.
SELECT * FROM plpo INTO TABLE lt_plpo
FOR ALL ENTRIES IN lt_plas
WHERE plnty = lt_plas-plnty
AND plnnr = lt_plas-plnnr
AND plnkn = lt_plas-plnkn
AND zaehl = lt_plas-zaehl.
DELETE ADJACENT DUPLICATES FROM lt_plpo COMPARING ALL FIELDS.
ENDIF.

*----------------------------------------------------*

* READ PLPO

*----------------------------------------------------*

IF NOT lt_plas[] IS INITIAL.

SELECT * FROM plpo INTO TABLE lt_plpo

FOR ALL ENTRIES IN lt_plas

WHERE plnty = lt_plas-plnty

AND plnnr = lt_plas-plnnr

AND plnkn = lt_plas-plnkn

AND zaehl = lt_plas-zaehl.

DELETE ADJACENT DUPLICATES FROM lt_plpo COMPARING ALL FIELDS.

ENDIF.

An ABAP sample code to retrieve the different link between PLKO and PLPO using PLAS can be :

READ TABLE lt_plko INTO ls_plko
WITH KEY plnnr = IV_plnnr " Input 
plnty = IV_plnty " Input .
IF sy-subrc = 0 .
" write your ABAP Custom Logic 
ENDIF.
" LINK BETWEEN PLKO AND PLPO -> PLAS
LOOP AT lt_plas INTO ls_plas WHERE plnnr = ls_plko-plnnr
AND plnty = ls_plko-plnty.
READ TABLE lt_plpo INTO ls_plpo
WITH KEY plnty = ls_plas-plnty
plnnr = ls_plas-plnnr
plnkn = ls_plas-plnkn
zaehl = ls_plas-zaehl.
IF sy-subrc = 0 .
" CUSTOM LOGIC HERE
ENDIF.
ENDLOOP

READ TABLE lt_plko INTO ls_plko

WITH KEY plnnr = IV_plnnr " Input

plnty = IV_plnty " Input .

IF sy-subrc = 0 .

" write your ABAP Custom Logic

ENDIF.

" LINK BETWEEN PLKO AND PLPO -> PLAS

LOOP AT lt_plas INTO ls_plas WHERE plnnr = ls_plko-plnnr

AND plnty = ls_plko-plnty.

READ TABLE lt_plpo INTO ls_plpo

WITH KEY plnty = ls_plas-plnty

plnnr = ls_plas-plnnr

plnkn = ls_plas-plnkn

zaehl = ls_plas-zaehl.

IF sy-subrc = 0 .

" CUSTOM LOGIC HERE

ENDIF.

ENDLOOP

Link Between PLKO and PLMZ

PLPO is the SAP Table Routine lines and PLMZ Table stores the relationship between the Routine line and the BOM Component.

*----------------------------------------------------*
* READ PLMZ

IF NOT lt_plpo[] IS INITIAL.
SELECT * FROM plmz INTO TABLE lt_plmz
FOR ALL ENTRIES IN lt_plpo
WHERE plnty = lt_plpo-plnty
AND plnnr = lt_plpo-plnnr
AND loekz NE 'X'
AND plnkn = lt_plpo-plnkn.
DELETE ADJACENT DUPLICATES FROM lt_plmz COMPARING ALL FIELDS.
ENDIF.
LOOP AT lt_plmz INTO ls_plmz WHERE plnnr = ls_plko-plnnr
AND plnty = ls_plko-plnty.
READ TABLE lt_plpo INTO ls_plpo_2
WITH KEY plnty = ls_plmz-plnty

plnkn = ls_plmz-plnkn.
IF SY-SUBRC = 0.
ENDIF.
ENDLOOP

*----------------------------------------------------*

* READ PLMZ

*----------------------------------------------------*

IF NOT lt_plpo[] IS INITIAL.

SELECT * FROM plmz INTO TABLE lt_plmz

FOR ALL ENTRIES IN lt_plpo

WHERE plnty = lt_plpo-plnty

DELETE ADJACENT DUPLICATES FROM lt_plmz COMPARING ALL FIELDS.

ENDIF.

LOOP AT lt_plmz INTO ls_plmz WHERE plnnr = ls_plko-plnnr

AND plnty = ls_plko-plnty.

READ TABLE lt_plpo INTO ls_plpo_2

WITH KEY plnty = ls_plmz-plnty
