This form lists all journal entries from Isah that have not been processed. The message explains why a journal entry could not be posted. One reason could be that the 'Blocked for manual changes' option was not set for the day books Integration of sales invoice entries, Integration of purchase invoice entries, and Integration of general entries. Once you remove the problem (in this case by activating the block), you can process the journal entries using the Release or Release all process.
