Need help in writing the code

Question

Hi,
My table data is as below.
Kunnr  BDAT EDAT  D1 D2 D3 D4 D5
1111    2001  2002   1      2    1      2     1
1111    2003  2008   1      0    4     1      2
1111    2008  2011   1      1    1     1      1
2222    2003  2008   1      2    2             2
2222    2008  2011           1    2     1      1
Here for kunnr  between begin and end date we have to caluclate the dependencies. (I.e if there is any value in D1or D2 or D3orD4 it shoulbe counted as 1. of it is zero or blank then it should not be coutned).
for Ex: for 1111 between 2001 & 2002 tot dependencies are 5.            
           for 1111 between 2003 & 2008 tot dependencies are 4.
in this scenario what will be the best way of writing the code. Do we need to check each and every field when counting the Sum value or and simple way to improve the performance.
Regards,
Vishnu

Answer 1

Hi Vishnu,
Here, you will have to check for the range of your begin date & end date. If it comes in the said range, then you simply have to add the values of your D1, D2,... DX values which you can store in some variables by setting out a flag as one counter for each.
If your case is satisfied for any of the date range, then just check for the flag values which are satisfied & add them or display the sum of the number of counters.
@Ambujavalli, At End Of won't work here because the date ranges given by Vishnu will differ.
Those statements are useful in a case when suppose for the same field value, you need to calculate a particular sum.
Here, that is not the case. Hence, AT First & At End Of won't work.
Thanks,
Gayathri.
