IDOC Status 51


Whenever i post an idoc from system A to B (MATMAS), the inbound idoc ends with a status 51 with message 'Function module not allowed'. Now the FM used is a Z FM. I have checked the following steps but found no error :-

1 WE20 , partner profile checked correctly

2 we42 , FM assigned correctly

3 WE57 , FM assigned to message type with correct business object and direction.

4 Table TBD51 , FM exists with correct entries.

Also , when i run the failed idoc in WE19 with the same FM , it posts correctly with status 53.

Please help me on this problem.
