using function module Read_text

Hi Experts

I Am trying to extract info record Purchase order text.

I am using the function module " Read_text".

The input parameters which I am using are

CLIENT <cl>

ID BT

LANGUAGE EN

NAME <inforecord nopurchase orgcategoryplant>

OBJECT EINE

However I find an inconsistency in data extraction.

If the Purchase order text is automatically populated from material master in the inforecord the function module

does not return back any data.

( There is status"*" on screen against such inforecord text)

When the Purchase order text is changed at inforecord level , the function module returns the correct data

(There is status no "*" on screen against such inforecord text)

Please do advise how do we get the correct data for both the baove scenarios.

Thanks and Regards

Vikrant
