| Key Fields | SAP Routines Tables Key Fields |
|---|---|
| PLNTY | Task List Type Number (for orders from AFKO, for notifications from |

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
WHERE plnty = lt_plko-plnty
AND plnnr = lt_plko-plnnr
AND plnal = lt_plko-plnal
AND loekz NE 'X'.
DELETE ADJACENT DUPLICATES FROM lt_plas COMPARING ALL FIELDS.
ENDIF.
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.
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
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
plnnr = ls_plmz-plnnr
plnkn = ls_plmz-plnkn.
IF SY-SUBRC = 0.
ENDIF.
