Trying to Upload the Initial Stock, Transaction Code MB1C and Movement Type 561 through LSMW.
While recording the fileds, system giving a message of Code Block.
Please let us know about Code Block while uploading the Initial Stock.
I think you are doing recording method. When you do recording remove a small tick which you can see at right hand side without any name. Then You will not get coding block
Assuming you are using batch input recording method, run though the transaction online yourself, you should encounter the same issue and hence how to resolve.
