AET Error while Creating new field

HI All,

I am facing a problem while creating new fields in the Campaign UI via AET. We are using CRM 7.0 system.

I am creating this field in the Campaign Header (MKTPL_CPG). Just as I select the package and BO, Click OK, it gives the below BSP Error:

The Status field returns the value as 'I'.

Could any body please tell what might be the issue behind this error.

Thanks in advance!

Regards,

Swati
