Pick last 4 values from another table

girish_talele — Fri, 12 Dec 2014 14:03:27 GMT

Dear Experts,

I have two tables as shown below.

First table is showing Production order Details & second is showing Billing Table.

In few Billing No, Production order is linked, but in few it is missing.

We have a requirement - If Production Order is missing in Billing Table then pick last 4 (descending order) production orders of same material & populate in the Billing Table.

Please suggest how to map the requirement. Sample qvw is attached herewith.

Hi Girish,

Could you test the script below and come back to know if it's your expected result :

Prd_Ord:

LOAD * INLINE [

PrdOrd, B_Material, P_Qty

P1, M1, 10

P2, M2, 20

P3, M3, 30

P4, M4, 40

P5, M4, 50

P6, M4, 60

P7, M4, 70

P8, M4, 80

P9, M4, 90

P10, M4, 100

P11, M5, 110

P12, M5, 120

P13, M5, 130

];

Join

Billing:

LOAD * INLINE [

BillNo, B_Material, P_PrdOrd

B1, M1, P1

B2, M2, P2

B3, M3, P3

B4, M4,

B5, M5,

];

See attached qvw for a possible solution.

Thanks Gysbert Wassenaar,

But we wanted to fetch (last 4) production orders where the link was missing.

Just modify & twisted you solution a little bit & get the desired results.

I want to know is there any better way to handle this requirement? .

Regards,

Girish.
