I saw this too. If you DFDM GL_CompanyBatchOptions prolly you will see these 3 keys missing:
P/O01, P/O02, P/O03
The key is ModuleCode + BatchType. For BatchType:
01 - Receipt of Goods
02 - Returns of Goods
03 - Material Req
In my case it was B/M instead of P/O but same principle. I created a new key from existing and now Options screen was okay. Also can restore the file from backup but then you'll have to set the NextBatchNo properly on the non-P/O batches.
