IDOC reprocessing issue through BD87

Hello,

I have a custom IDOC type and custom message type for an outbound IDOC. Developed a FM to retrieve data for segments and using MASTER_IDOC_DISTRIBUTE FM to generate Outbound IDOC. Everything is good.

Issue is while trying to reprocess the IDOC. Doing this through BD87. But it is changing the original IDOC status to 33 and also creating new IDOC.

My Requirement is to reprocess the same IDOC and processing it through the FM created for this IDOC type.

Please let me know how can I achieve this.

Thanks for all the help
