Dear SAP expert
In our MDG system we are facing an issue when we are trying to add a new EAN number to existing material.
In material 000000000000265975 there is existing EAN number 00363459348049 of GTIN 14 type.
We need to add a new non main EAN number 0363459348049 of EAN-13 type .
When we're entering the new EAN, additional leading 0 is being added and the following error message is received "Entity EA/00363459348049 already exists. Correct entry".
This is currently blocking the business in EU serialization data preparation (GTIN 14 cannot be loaded if there is an EAN13 already saved in an SKU - GTIN14 is built only by adding a leading 0 to EAN13 - what SAP recognizes as a duplicate and gives an error)
