You say that the title of your current position is misleading--even though you're a "finance executive," all you're doing is "data entry." Also, you're disappointed that the "growth opportunities" are lacking at your current company. Did I understand you correctly?
My advice to you is to take a closer look at your current company. All organizations are dynamic. Some more than others. By that I mean that the roles to play within the organization and the tasks to accomplish are always changing.
Maybe there are opportunities within the company that you have yet to see. Are there any ways that you can take the initiative to add value? Here are some examples: figure out a way to streamline a workflow to make it more efficient; solve a problem that no one else has been able to solve due to lack of time or resources; discover a new market for an existing product or service or develop an entirely new service/product. Give of yourself freely first, then, without expecting it, watch the rewards come your way.
Once you've made a sincere effort to find ways within your current organization to add more value, you'll be in a much stronger position to negotiate for a new role or a raise. If your current company is so rigid that there is no room for you to be more entrepreneurial within the company, perhaps then it would be time to look elsewhere. At the very least, you can use a job offer elsewhere as leverage to negotiate a better situation in your current company.
In the long run, you want to put yourself in a position where you have the most chances to grow professionally, where your supervisors facilitate and reward your willingness to serve the company's interests by adding more and more value.
Hope this helps,
