Logic problem in table

Wed, 28 Aug 2013 07:06:08 GMT

Dear All,

I have this kind of data:-

Model	Type	Material Code	Amt
S55	Raw	1	12
S55	Raw	2	15
S55	Raw	3	47
S55	SFG	6	25
S55	SFG	23	20
S55	SFG	45	16
S55	FG	250	123
S56	Raw	1	12
S56	Raw	14	25
S56	Raw	16	78
S56	SFG	23	20
S56	SFG	50	96
S56	SFG	63	47
S56	FG	78	15
S57	Raw	1	12
S57	Raw	2	15
S57	Raw	99	96
S57	SFG	45	16
S57	SFG	30	25
S57	SFG	9	12
S57	FG	250	123

now my question is:-

my material ( 1)- occurs in all three model. So when i want to display the data in chart, i want amount for the material against model where it occurs first., and if the same material occur in other model then the amount should be zero.

For example;

Material code starting with 1 occurs in all three model i.e S55,S56,S57 and its amount is 12.So i want amount against S55 model because the material first occurred there and for the remaining model it should show zero value.

Please Help me out.....

You can probably utilize the exists function like this

Load Model, Type, [Material Code],Amt, if(exists(Amt), 0, Amt) as ModifiedAmt

From...

and then use the field ModifiedAmt in your table. It should know only hold a a value above 0, for the first record with a unique Material Code.

Hi,

You could reload your table in the script to set to 0 those values that are repeated in the same model:

NewTable:

Noconcatenate LOAD

Model,

Type,

[Material Code],

if(Previous([Material Code])=[Material Code], 0, Amt) as Amt

Resident YourTable

Order By [Material Code] asc;

Good Luck.

@ VishalWaghole

I cannot fit ur formula on back end because fields are from different table and they cannot be brought into one
