I have created an inbound specification for a flat file and outbound for xml. I have tested the inbound specification with a csv file and its fine also mapped the documents and did some test its also fine.

I have created a flat file envelope in BizTalk messaging manager. When I created my receive function and use the envelope I receive the following error on the function:

0xc00ce558 [0x1416] The specification failed to load. See the following messages for details.

 [0x1a20] The envelope "HeatFILES" could not be loaded. A possible cause is that the specification is not valid. Configure a valid envelope specification.

 [0x1436] The envelope name "HeatFILES" does not reference a valid envelope for the BizTalk Server parser. Either the envelope name does not exist or there is an envelope specification attached that is not valid.

 [0x1416] The specification failed to load. See the following messages for details.

 [0x1730] Suspended Queue ID: "{F63EBE66-EEF4-40B8-A08A-60B9D6E66A81}"

 [0x1416] The specification failed to load. See the following messages for details.

Can anyone help in resolving this error.

Thanks
