Hybris Datahub delete Raw entry

[mainroad]

Hello experts, I need your help because our datahub is getting stuck with RawHybrisOrders.

In composition phase we are getting a database error:

https://answers.sap.com/questions/12878270/datahub-data-truncation-data-too-long-for-column-i.html

So composition fail, and next time composition starts take same data from pool. So it gets another error, and does no composition.

Next time takes again same raw data and began the process again. The process is stuck and no futher raw items are processed.

How can I delete that raw item that in coposition status generates an error?

Regards.
