How To Fix DDACT035 - Length of VARDATA field cannot be changed

SAP Error Message - Details

• Message type: E = Error

• Message class: DDACT - Messages for Activating Dictionary Objects

• Message number: 035

• Message text: Length of VARDATA field cannot be changed

What causes this issue?

You wish to change and transport an existing table pool.

System Response

This will cause an activation error for the following reason: In
Unicode and non-Unicode systems, the same table pools have different
definitions in the Dictionary. Transporting into a non-homogeneous
landscape with both system types would cause conversions, even if the
table pool was not changed structurally in the original system.
For this reason, a transport is not possible. This is prevented when
the system prevents you from creating a new version of the table pool.

How to fix this error?

Reset the table pool to active status.

Procedure for System Administrators

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.
