CL_SY_IMPORT_MISMATCH_ERROR for extractor

hi Experts,

First up I am sorry if I am posting this to wrong forum or if u find this as a repost because I absolutely have no idea of the specifications of BW forums and I dont know where i wud get the soltuion from.

I am an abaper and have got this issue for BW to sort. I am using RSA3 transaction for extractor 2LIS_11_VAHDR and there in the Q § A i m getting the error of CL_SY_IMPORT_MISMATCH_ERROR . I do understand that its a mismatch of structure. Now the interesting part comes. the same transaction with the same structure 2LIS_11_VAHDR works fine in Development and it has been transported to Testing. I do not understand where to find the error since the structures too are same in both of the system.

Any solutions??

thanks ,

Gaurav
