Message no. KD514_Complete PA transfer structure Z1

Hello SAP Gurus,

I have a PA transfer structure created for settling the production variances.

Created one assignment line per each variance category.

I have created a cost element group "ALLCOSTELE" and assign to each of the assignment lines and assigned the relevant value field also.

However I am getting below error:

"There is no value field assignment for cost element 510000 / variance
category  in PA transfer structure Z1, or

PA transfer structure Z1 has no assignments, or

No "Origin" is maintained for the assignments in PA transfer structure Z1
(cost element group and, if applicable, variance category)"

Not sure what am I missing as cost element 510000 already exist in the cost lement group "ALLCOSTELE"

Any isights would highly be appreciated.

Thank you

Best Regards

Surya
