Hi,

Donot give b~assetflg condition in where clause instead select it into ITAB and then filter it.

Going by the error you cannot use B~ASSETFLG eq '0'. in the where condition

Try with inner join

Hi,

Just use Inner Join as below.

SELECT A~ASSETNO INTO ASSETNO-ASSETNO FROM ZASSET_DETAILS AS A <b>INNER JOIN</b> ZASSET_FLAG AS B

ON A_{ASSETNO EQ B}ASSETNO

WHERE A_{ASSETYPE = 'Laptop' and B}ASSETFLG eq '0'.

Hi,

In the left outer join , u can not put condition on right hand table

SELECT A~ASSETNO INTO ASSETNO-ASSETNO FROM ZASSET_DETAILS AS A LEFT OUTER JOIN ZASSET_FLAG AS B

ON A_{ASSETNO EQ B}ASSETNO

WHERE A_{ASSETYPE = 'Laptop' and <b>B}ASSETFLG eq '0'.</b>.

Hi Muthu,

We cannot give the field for the right hand table in the condition. Because.

- left outer join will get everything which is on the left.

- where condition should be on left and table and on condition on right hand table.

- on left outer join... if you have no entries in the right hand table matching to the left hand table then it joins the table but gives a null entry correpsong to d missg value...

So, that is the reason you are getting that error... please read help on joins and will will get a pictorial solution to you problem.
