Record Insertion Problem

Question

Using the following code, am populating the internal table z_ZI2DLVSTORE.
SELECT SINGLE * FROM VBFA
INTO y_ZI2DLVSTORE
WHERE VBELN = IXLIPS-VBELN AND POSNN = IXLIPS-POSNR.
x_ZI2DLVSTORE-VBELV = y_ZI2DLVSTORE-VBELV.
x_ZI2DLVSTORE-POSNV = y_ZI2DLVSTORE-POSNV.
x_ZI2DLVSTORE-VBELN = y_ZI2DLVSTORE-VBELN.
x_ZI2DLVSTORE-POSNN = y_ZI2DLVSTORE-POSNN.
x_ZI2DLVSTORE-RFMNG = y_ZI2DLVSTORE-RFMNG.
SELECT SINGLE PRODUCT FROM ZI2PEGPROM
INTO CORRESPONDING FIELDS OF x_ZI2DLVSTORE
WHERE VBELN = x_ZI2DLVSTORE-VBELV.
SELECT SINGLE SELLER FROM ZI2DLVPROM
INTO CORRESPONDING FIELDS OF x_ZI2DLVSTORE
WHERE VBELN = x_ZI2DLVSTORE-VBELV.
If not x_ZI2DLVSTORE-VBELV is initial.
z_ZI2DLVSTORE-VBELN = x_ZI2DLVSTORE-VBELV.
z_ZI2DLVSTORE-POSNR = x_ZI2DLVSTORE-POSNV.
z_ZI2DLVSTORE-VGBEL = x_ZI2DLVSTORE-VBELN.
z_ZI2DLVSTORE-VGPOS = x_ZI2DLVSTORE-POSNN.
z_ZI2DLVSTORE-PPOS = x_ZI2DLVSTORE-PRODUCT.
z_ZI2DLVSTORE-SELLER = x_ZI2DLVSTORE-SELLER.
z_ZI2DLVSTORE-DELQTY = x_ZI2DLVSTORE-RFMNG.
z_ZI2DLVSTORE-WADAT = SY-DATUM.
z_ZI2DLVSTORE-GIFLAG = ' '.
Here, my record is ready to get uploaded into master table
Then, using below code, am updating the master table ZI2DLVSTORE.If record already exists, it will update or it will create a new record - thats my requirement
if z_ZI2DLVSTORE-POSNR < '900000'.
MODIFY ZI2DLVSTORE FROM table z_ZI2DLVSTORE.
endif.
endif.
clear z_ZI2DLVSTORE.
But, my table ZI2DLVSTORE is not accepting that entry. Why? Plz suggest.

Hi,
  According to ur code it looks you are trying to insert work area data  but not internal table. (in the logic no Append statement, and in the last line u have used  CLEAR statement 'clear z_ZI2DLVSTORE.' )
for updating workarea syntax is
MODIFY ZI2DLVSTORE  FROM z_ZI2DLVSTORE.
