TEXT replication from ECC to CRM.

Hie Guys, we have a problem with texts replication with regards to sales order.

Problem is, When a sales order is created we will have text atomaticaly populated in the texts tab of item level. This comes from Materiel master.Now Problem is once we release (to ECC) the sales order, This text gets dissappeared.

Does anyone know why this happens?

thanks and regards,

Lata.
