Activating Transformation in BI content

Hi,

Can we re-install the transformation in BI content for 2LIS_13_VDITM to infocube 0SD_C03? Although in our case, we have added custom fields in 0SD_C03 already.

Will it be safely to delete the transformation and re-install again without reinstalling the 0SD_C03 infocube?

Because, we are having trouble in activating the transformation. We are encoutering ASSERTION was violated.

What happened?

     In the running application program, the ASSERT statement recognized a

     situation that should not have occurred.

     The runtime error was triggered for one of these reasons:

     - For the checkpoint group specified with the ASSERT statement, the

       activation mode is set to "abort".

     - Via a system variant, the activation mode is globally set to "abort"

       for checkpoint groups in this system.

     - The activation mode is set to "abort" on program level.

     - The ASSERT statement is not assigned to any checkpoint group.

Error analysis

     The following checkpoint group was used: "No checkpoint group specified"

     If in the ASSERT statement the addition FIELDS was used, you can find

     the content of the first 8 specified fields in the following overview:

     " (not used) "

     " (not used) "

     " (not used) "

     " (not used) "

     " (not used) "

     " (not used) "

     " (not used) "

     " (not used) "

Thank you.
