HFM User defined1,User Defined2,User Defined 3

Question

Hi Peers,
Please explain me clearly the importance of User defined1,2,3 in HFM and as well as rules.We find this attribute every where. Where to start? how to use? When to use? what is the Answer we have to explain as soon as we pose this Question

Answer 1

They are UserDefined attributes . Can be used to Convert at special Exchange Rates also other possible use can be to transfer or move data from account to the specified account in User Defined Attribute.
Eg :
1) Transfer from 1 account to another
Values of Account xyz need to flow to account pqr , in that case i can specify pqr in "Userdefined1" attribute and while writing rules check if userdefined1 has any values by hs.Account.UD1("xyz") . This will ideally retrieve pqr . And by simple Hs.exp syntax we can move the values from xyz to pqr . This the above case we need not load the data multiple times by data load . Automation can be done .
2) Historical Rate translation:
Similarly we can translate as special Exchange rate by specifiying Special Exchange rate account in any of the Userdefined Attribute . Share capital generally goes at special or historical rate . Hence translation can be achieved at historical rate be using User defined attributes .
Hope it clarifies your doubt on userdefined attributes and its uses .
