Committ Work is failing

Question

Hi All,
My program is actually converting General Receipe to Master Receipe and updating the data base.All the FM are working properly and no where my sy-subrc is failing for any FM and work is committed at the end of every general receipe, but after crossing some 100+ records the FM are working properly(i.e the sy-subrc is not failing) in saving the data but after that when it encounters the COMMITT and WAIT statement its not happening.After this COMMITT statement its giving a sy-subrc - 4.This is not happening(i.e sy-subrc is not failing for commit and wait) for the same records if the number of records is less than 100. This commit is causing a problem only after reaching some 100+ records.
So kindly let me know wat might be the problem.
Thank you in advance.

The problem is solved now.
The primary key of the header table to be updated  constitute RGUID , ICNT , RECNT.
My object has to convert 100's  GRu2019s  so what it was  doing (standard FM) is increasing the counter of RCNT (version).
The problem is we have field RECNT(version) which of type NUMC 2 so it can have a max value of 99 and after that its becoming 00.
So the key is getting repeated and the update is failing as RGUID is not changing.
The new RGUID is not generating every time as the standard program reads  a global table which has contains the list of all converted GRu2019s.
Every time its reads the global table and if no entry is present then it will create a new RGUID or else increases version number RCNT.
So we made a implicit enhancement to clear that table every time to generate new GUID every time.
