created udf in ledger master now wanna fetch details from a group of ledger to it

The "Group" of Ledger is already there in Ledger Master .... so what exactly do you need a new Field/UDF for ??

 

Make a Collection / Table of Ledgers --- Filter it -- if belongs to Group named "broker"

Add this LINE in your field --- Table : YourTableName

 

I take it to understand that you are new to coding and making good efforts to learn, but simply copying code will not work always -- even if you do copy -- then try to understand the coding logic. It will help you learn faster and better.

[Field:Broker]
Use:name field
Set As : $$Value
Table : brokerlist
Show Table : always
set always : yes
Storage:Broker
Width:30

[Collection : brokerlist]
type : ledger
filter : onlybroker

[system : formula]
onlybroker : $Parent:Ledger:$Name = "Broker"

 

You cannot FETCH a FIELD in your collection only UDFs can be fetched.

Study the Field -- [Field: EI ValueSubTotal] in Tally Developer ►► see how the value has been derived.

Compute in the same manner in your collection.

 

If you are referencing a field -- it has to be in the same report -- and secondly you have to use # not $.

Most importantly, you have not read the last line of my post -- I asked you to COMPUTE in your report Collection.

Now I do not know your Report and full code and I do not know how and where you are trying to get the Value -- so you need to workout the same on your own. If you are outstation and still working you can download Developer -- it is not a big installation.

Another hint : Use Function $$CollAmtTotal to compute the value.

 

E-Way bill will be associated with a SALES VOUCHER not the Ledger Account.

make a Collection of Sales Vouchers -- compute/extract the E-way bill information and call for it in your Main Report collection.
