Question:
Hi All,
When I do LT03 (Cr. TO for Delivery), I get the following error. I checked the SU1000000000 in LS33 and I find no blocking indicator set for both Putaway or picking.
I checked SAP Help and OSS and cud not find an answer.
Below is the copy of the erroe msg detail from SAP :
"Storage unit 1000000000 is blocked for stock removals
Message no. L3 219
Diagnosis
You are attempting to remove stock from a storage unit that is currently blocked for pickss.
Procedure
Check the storage unit number that was entered or the status of the storage unit.
Check storage unit"
Please suggest a way to post TO.
Regards
Answer:
Check LI06 if storage type is blocked for count
or
LS12 if storage type is blocked
or
LS06 if storage bin is blocked
or
LS07 if stock is blocked
