Refresh using CS_BOM_EXPL_MAT_V2 2 times

Question

Hi,
my problem is:
1. use fm CS_BOM_EXPL_MAT_V2 to get BOM data.
2. I modify the BOM using a Batch Input
3. use fm CS_BOM_EXPL_MAT_V2 to get the BOM updated.
the FM in the 3th step load the old data and not the updated BOM.
Any suggest?
Can i clear the program cache?

Hello,
I'm answering to this threat even though it's 5 years old just in case somebody is looking out for the solution like I was a couple of weeks ago.
The FM CS_BOM_EXPL_MAT_V2 calls internally another FM called GET_STPO.  Inside GET_STPO you will find structure STPOCTL which will contain material's information for the previous run of CS_BOM_EXPL_MAT_V2. Also, FM GET_STPO calls FM GET_STATS which will contain the structure STASCTL; both these structures need to be cleared in order for the Function Module to retrieve fresh data from the database, instead of just returning the same data that was returned in the first run.
In the Function Group CSIO, which contains all these Function Modules, there's a Function Module in charge of clearing these structures plus another internal tables which will contain the material's information, you need to call this FM right after your 1st iteration in order to clear the buffer. The Function Module is CSIO_REFRESH_BUFFER or CS_IO_BOM_BUFFER_SMASH, depending on your SAP implementation.
Hope this helps anyone
