Flatfile receive pipeline

Hi

I have 2 orchs.
One receives an XML file and uses a map to convert it to a CSV file.
It then uses a send pipline with a Flat File assembler that writes a CSV file to the HDD.
This works fine.

The second orch has a receive pipeline that picks up the CSV file and processes it.
This pipeline uses a FF disassembler to receive the document.

Both the “send” and “receive” FF pipelines use the same schema.
The “send” pipeline uses the FF schema to produce the file and the “receive” pipeline uses the same FF schema to consume the file. And yet I am getting this error whenever the “receive” pipeline picks up the file:

“
Description:
There was a failure executing the receive pipeline: “In_CSV” Source: “Flat file disassembler” Receive Location: “C:\temp\Test\Out\*.csv” Reason: Unexpected data found while looking for:
‘\t’
The current definition being parsed is Invoice_Detail. The stream offset where the error occured is 220. The line number where the error occured is 2. The column where the error occured is 0.

The weird thing is that the receive pipeline is using a document produced by the send pipeline and they use the SAME schema – so why would the produced document not be appropriate for the receive pipeline?

TIA
