Here is one scenario.
this is related to Stock transport order between two plants.
In selection screen, vbrk-kunag and vbrp-werks(supplying plant) fields are there.
If vbrk-kunag field start with 'P'.I will get the second plant field By removing the initial 'P' in
now i have to read zplants table with vbrp-werks and vbrk-kunag(Without Initial 'P') field .If it matches i have to substitute vbrp-werks field with zplants-plnt.
Zplants table has fields like werks & reswk(supplying plant),plnt.
In the selection screen, If multiple values are entered in vbrk-kunag field, I have to check the above condition (match) again, If it is not matches just i have to add "P123" value and don't remove the original supplying plant(vbrp-werks) from the selection.
how can i write the above statements...
Thanks in advance.
