GTIN 100000000010926 does not match article and unit of measure

Hi,

I am trying to create sales order through bapi  SD_SALESDOCUMENT_CREATE

I am facing the error GTIN 100000000010926 does not match article  and unit of measure.

Why is it happening.If any configuration setting have to be done from SD angle. i.e GTIN mapping have to be done?

Please guide me.Please find the below screen shot,i have maintained EAN number in article.Also find the BAPI,both unit of measure (EA) and GTIN number is there .

Is that some thing we have to do like material determination???

I read the link,it states likes this EAN/UPC field in sales order is grey field | SCN
