DYNPRO_NOT_FOUND

Dear experts!

Now, I'm getting some issues.

When I run tcode: ME41 to create Request for Quotation then the system display error

"DYNPRO_NOT_FOUND".

Error analysis:

"The system attempted to use dynpro 0301 in program "SAPLXM06".

This dynpro does not exist."

How do I have to do to process the error?

Help me, please!

Best regards, Huy!
