Helloa,
You can try the following work around:
- create UDF at document level : Landed Cost Applicable Y and No with default value No
- Select Yes where ever applicable
- Once at landed cost, when you copy from GRPO and see the list of GRPO's: Go to form settings: select this UDF and you can even group by this UDF so that you would know which GRPO's are to be selected for Landed cost or not.
Hope this helps.
Thanks,
Joseph
