[Ram32]

for example :

<ID1>123XYZ  

<internalID>1</InternalID>

</ID1>

<ID1>123XYZ  

<internalID>2</InternalID>

</ID1>

<ID2>1234XYZ  

<internalID>1</InternalID>

</ID2>

quiestion 1:

if ID1 = 123XYZ  for the ID1, internalID everytime it auto incement by one(number range).

if ID2= 1234xyz for the ID2, internalID  again number start from 1(number range) .

is it possible through number range please let us know?

question 2:

if for InternalID number range(start from 1) reached till last number(99999999999999) how we can change number different from 1 to 9(14 times) for internalID
