Table for complaint storage statuses?

I am trying to download SAP QPRS table to get a list of [Physical sample , Material number, batch & Physical sample status (sample was stored & sample exist)]. I am using SAP .Net Connector to call the function module RFC_READ_TABLE to read the table QPRS.

But I cannot find the screen fields RQPRS-PRNVX and RQPRS-AUFBX that are related to physical sample status. Is it a structure, if so, how can I use RFC_READ_TABLE function module to ready these data.

I know I can use function modules to get physical sample status, but this is done material by material, which is very slow. I now to get whole table contact once to make it faster.

NB. Data needed is into SAP Tcode QPR3, in "Sample Storage" tab:

The flags are stored as statuses in the table JEST:

• Sample Was Stored: status I0363 (short code in Status History: "STRD")
• Sample Consumed/Destroyed: status I0362 (short code in Status History: "USED")

The table JEST has 3 important columns:

• OBJNR: "QP" followed with the sample number (12 digits, right-aligned, padded with zeroes on the left)
• STAT: status
• INACT: " " means that the status is set, "X" means that the status is not set
