Hi,
I recommend first that you free up the batch by resetting the MKDTOPST=0, BCHSTTUS=0.
Once done, print an Edit List of the batch.
From the looks of it, you are trying to post a batch where transactions have issues. Clearing activity and temp tables do not resolve this. You need to determine what is causing the batch to fail.
If the Edit List does not give you any errors, try creating a new batch and then transfer all transactions from the batch in question onto the new batch - then try posting again.
Let me know if you have further questions.
